Step 1 of 5: Calculate the sum of squared errors (SSE). Use the values b0=3.8024 and b1=0.2442 for the calculations. Round your answer to three decimal places

Step 2 of 5:

Calculate the estimated variance of errors, s2e. Round your answer to three decimal places.

Step 3 of 5:

Calculate the estimated variance of slope, s2b1. Round your answer to three decimal places.

Step 4 of 5:

Construct the 90%confidence interval for the slope. Round your answers to three decimal places. (lower endpoints, upper endpoints)

Step 5 of 5:

Construct the 99% confidence interval for the slope. Round your answers to three decimal places.(lower endpoints, upper endpoints)
